Application of grating shearography to the experimental analysis of a single fabric lamina under tensile loading

摘要

Grating shearography is an extension of moir interferometry where a shearing element is included in the imaging part of the setup. It is possible to obtain all three components of the in-plane strains, the in-plane rotation and the two out-of-plane slopes. The presented application is an experimental investigation of the mechanical behavior of a plain woven graphite fiber reinforced polymer composite lamina under tensile loading.
